nios2: get cpu node with of_get_cpu_node

2018-09-28T19:25:58+00:00

"device_type" use is deprecated for FDT though it has continued to be used
for nodes like cpu nodes. Use of_get_cpu_node() instead which works using
node names by default. This will allow the eventually removal of cpu
device_type properties.

Also, fix a leaked reference by adding a missing of_node_put.

nios2: Add CDX support

2017-05-08T08:59:19+00:00

Add support for the CDX Code Density Extensions present in
Nios II R2 . This introduces new 16bit instruction set to
improve code density while retaining support for the 32bit
Nios II R2 instructions.

nios2: Add NIOS2_ARCH_REVISION to select between R1 and R2

2017-05-08T08:59:19+00:00

Allow user to select between Nios2 R1 and R2. Since R1 and R2 are
not binary compatible, we cannot have a single kernel binary and
there is no point in having DT property for discerning these two.

nios2: use of_property_read_bool

2016-10-06T10:19:16+00:00

Use of_property_read_bool instead of open-coding it as fpcu_has.
Convert the members of struct cpuinfo from u32 to bool accordingly as
they are only used as boolean anyhow.

nios2: cpuinfo: remove use of seq_printf return value

2015-04-15T23:35:24+00:00

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")

read by using IS_ENABLED instead of #ifdefs.
